Abstract

The utility model relates to a die for V-shaped bending, in particular to a die for bending an aluminum product into a V shape and preventing scratches. According to the die for bending the aluminum product into the V shape and preventing scratches, a forming male die and an upper plate clamp are arranged on an upper die base, two female die swing blocks, a female die swing block fixing device and a female die swing block resetting device are arranged on a lower die base, and the two female die swing blocks can rotate around the centers of rolling shafts of the female die swing blocks respectively and interact to form a 90-degree angle; when a punching machine moves downwards, the forming male die of the upper die base is driven to move downwards until the two female die swing blocks on the lower die base are rotated by the forming male die around the centers of the rolling shafts to form a 90-degree shape, the punching machine moves upwards, the female die swing block resetting device enables the female die swing blocks to be reset, and then punching is completed once. According to the structure, the die for bending the aluminum product into the V shape and preventing scratches has the advantages that scratches are avoided, and therefore an aluminum plate having a strict requirement for the appearance can be formed; rebounding of the product with a large R angle at the forming bending height can be reduced; the bending angle can be adjusted optionally within the range from zero degree to 90 degrees.

Description

The bending of aluminium V-type is without scratch mould

Technical field

The utility model relates to a kind of V-type Bending Mould, and particularly the bending of a kind of aluminium V-type is without scratch mould.

Background technology

Aluminium sheet aluminium product is widely used in various fields with its unique character.For example, be widely used in power supply upper and lower covers or main frame upper and lower covers.In the time that aluminium sheet aluminium product is applied in power supply upper and lower covers or main frame upper and lower covers, all need aluminium sheet aluminium to strike out V-type.In the market, the mould that aluminium sheet aluminium is struck out to V-type mainly comprises following structure: upper die and lower die, and upper die and lower die form to roll by guide pillar and guide pin bushing and coordinate, and patrix is provided with staking punch, and counterdie is provided with V-type groove.When work, aluminium sheet aluminium is placed on counterdie, then patrix drives the downward die stamping of staking punch, gives the certain stamping press of aluminium sheet aluminium, and repeatedly punching press back and forth, until aluminium sheet aluminium is washed into V-type., there is following defect in the mould of this kind of structure:

1, when bending, be by patrix drive staking punch to the aluminium sheet aluminium on counterdie repeatedly back and forth punching press realize, so the bending lateral surface of aluminium sheet aluminium has scratch, particularly, when moulding R angle is less, scratch is more serious;

2, bending precision is not suitable for the product of large R angle product with large negative angle; ,

3, the inapplicable bending edges of this bending keep away position many or bending root have protruding product.

In view of this, the inventor conducts in-depth research aluminium sheet aluminium product bent mold structure, and this case produces thus.

Utility model content

It is a kind of without abrading and can use the aluminium V-type bending that is suitable for multiple bending angle without scratch mould that the purpose of this utility model is to provide.

The purpose of this utility model is achieved by the following technical solution: the bending of aluminium V-type is without scratch mould, comprise upper bolster and die shoe, upper bolster is provided with guide pin bushing, die shoe is provided with guide pillar, guide pin bushing and guide pillar form to roll and coordinate, it is characterized in that: on described upper bolster, be also provided with forming convax mould and upper plate holder, forming convax mould is pressed from both sides and is fixed on upper bolster by upper plate, described die shoe be provided with two can be respectively around roller bearing central rotation separately mutual become die centering block, die centering block fixture and the die centering block resetting means of 90 degree.

As a kind of improvement of the present utility model, described die centering block fixture comprises two baffle plates and roller bearing, and two baffle plates are parallel to each other and perpendicular to die shoe, die centering block two ends are separately fixed on two baffle plates by roller bearing.

One improve as of the present utility model, described die centering block resetting means comprises top board and several springs again, and described top board is positioned at the below of die centering block, and upper end and the top board of spring join, and the lower end of spring is fixed on die shoe.

The beneficial effect that the utility model is obtained: aluminium V-type of the present utility model bending without scratch mould by upper bolster, establish forming convax mould and on plate holder, on die shoe, establish two can be respectively around roller bearing central rotation separately mutual become the die centering blocks of 90 degree, die centering block fixture and die centering block resetting means, when moving downward, punch press drive upper die forming punch to move downward, until forming convax mould by two die centering blocks on die shoe around 90 ° of shapes of roller bearing central rotation moulding, punch press is upwards walked, die centering block resetting means resets die centering block, complete a punching press, the aluminium V-type Bending Mould tool of this kind of structure has the following advantages:

1, without scratch, the plastic aluminium sheet that outward appearance is had to strict demand;

2, can reduce the larger product resilience in R angle of moulding bending height;

3, can in 0-90 °, adjust arbitrarily the angle of bending.

Brief description of the drawings

Fig. 1 is the utility model die opening state structural representation;

Fig. 2 is the utility model matched moulds view.

Detailed description of the invention

In order further to explain the technical solution of the utility model, below in conjunction with accompanying drawing, come by specific embodiment that the utility model is elaborated:

Referring to Fig. 1 and Fig. 2, the bending of aluminium V-type, without scratch mould, comprises upper bolster 1 and die shoe 2, and upper bolster is provided with guide pin bushing 11, forming convax mould 12 and upper plate holder 13, and forming convax mould 12 is fixed on upper bolster 1 by upper plate holder 13.Between forming convax mould 12 and train wheel bridge 13, adopt matched in clearance, gap is 0.015mm.Forming convax mould 12 materials are CR12, process hardness HRC58 ~ 60, adopt fast wire winding processing.Die shoe 2 be provided with 21, two of guide pillars can be respectively around roller bearing central rotation separately mutual become die centering block 22, die centering block fixture and the die centering block resetting means of 90 degree.Die centering block fixture comprises that two baffle plates 231 and roller bearing 232, two baffle plates 231 are parallel to each other and perpendicular to die shoe 1, die centering block 22 two ends are separately fixed on two baffle plates 231 by roller bearing 232.Die centering block resetting means comprises top board 241 and several springs 242, and top board 241 is positioned at the below of die centering block 22, and the upper end of spring 242 and top board 241 join, and the lower end of spring 242 is fixed on die shoe 2.

When moulding aluminium V-type, punch press moves downward and drives upper die forming punch 12 to move downward, until forming convax mould 12 by two die centering blocks 22 on die shoe around 90 ° of shapes of roller bearing central rotation moulding, referring to Fig. 2, now, top board 241 suppresses spring 242 downwards, and aluminium 3 is pressed into V-type, in the time that punch press is upwards walked, spring starts to reset, and by upwards jack-up of top board, top board drives die centering block to reset, complete a punching press, the aluminium V-type Bending Mould tool of this kind of structure has the following advantages:

3, can in 0-90 °, adjust arbitrarily the angle of bending.

Above-described embodiment and graphic and non-limiting product form of the present utility model and style, suitable variation or modification that any person of an ordinary skill in the technical field does it, all should be considered as not departing from patent category of the present utility model.
